To tZZ whom it may concern:

Be it known that we, HELIODOR ROSTIN, residing at No. 9 Neue Ansbacherstrasse, and OTTO THIELBEULE and HUGO WARSCHAUER,

residing at No. 1 Markgrafenstrasse, Berlin,

Prussia,German Empire,subjects of the King of Prussia, Emperor of Germany, have jointly invented certain new and useful Improvegas-lighting apparatus of that class in which the gas issuing from the burner is lighted by a constantly-burning auxiliary or b v-flame. For admitting the gas from the conduit to the burner a valve or cock must be opened; and our invention consists in providing improved means for opening the valve or cock from any suitable distance-for instance, from lthe gasworks-th us dispensing with the necessity of lighting every single lamp or lantern by the work of hands.

v The improvements of ourinvention particularly have reference to apparatus of the kind by which the valve or cock of the burner is opened and closed through the agency of a bell arranged in proximity to the burner, said bell being lifted from its normal position by an increased pressure of gas temporarily made to flow through the conduit from a station or from the gas-works.

The accompanying drawing represents in sectional elevation a gas-lighting apparatus constructed according to our invention, and a lamp-burner to be lighted by the same.

a is a bell, moving in a suitable liquid seal contained Within circular grooves b c of a suitable block'd. Within the upper side of said block two other iiuidor mercury seals e f are provided, into which plunge the cupvalves i and 7c, suspended to a double-armed lever m. Into the cup-valve t' opens from below a pipe g, connected to the gas-pipe below the burner cock or valve, and into the other valve k opens another pipe h, leading to the open air. The two valves i and 7c are of different weight, whereby the valve normally plunges into its respective seal e, while the other valve Itis lifted free from its respective seal f.

The weight of the cup-valve e' is so calculated that the normal pressure exist-ing in the gas-conduit will not lift it from its seal; but any pressure exceeding the normal pressure in the conduit will cause the valve z' to be raised from its seal, and thereby the other valve 7e will be lowered by the lever m and plunged into its seal f, thus shutting off the escape-pipe h. Y

For lighting the lamps or lanterns of a conduit from a distance-for instance, from the gas-works-an additional or surplus pressure is made to flow through the conduit-pipes of the plant, and the said'surplus pressure, entering below the valve 't' through the pipe g, will raise said valve and the gas will issue into the bell a, causing the same to rise in its fluid or mercury seal. The top of said bell a is connected by a chain n or wire or cord to a lever o, carrying a pawl p, which engages a ratchet-wheel q. The aXis of said ratchetwheel carries a star-wheel r, which as it is being turned will bear against a spring t, thereby deflecting said spring and opening the valve s, carried by said spring; but the throw of the lever o, caused by therising motion of the bell a, might as well be transmitted by any other mechanical means `to the valve s or any valve or cock of the burner. Through the open valve s the gas issues from the burner u and is lighted by the by-llame c, which permanently burns in a known manner.

As soon as the surplus pressure [lowing through the gas-conduit will cease the valve e' will come down and plunge into its seal e, while at the same time the lever fm will raise the valve k from its seal f to allow the escape of the gas from the bell a into the open air. The said bell a accordingly will return to its normal position; but in its descent the lever o will not turn the ratchet-wheel, as the pawl p slides freely over the curved side of the indentations. The'valve s accordingly will remain open. By this means all burners of a gas-conduit may be lighted at the same time by sending a temporary surplus pressure of gas through the conduit. The same means may equally serve for extinguishing the lamps IOO or lanterns of the conduit by sending another temporary surplus pressure through the conduit. By doing so the bell a will be raised again, as before described, and the lever o accordingly by its upward stroke will 'again turn by one tooth the ratchet-Wheel q and the star-wheel r. The projecting arms of said star-wheel are so placed that the spring t, having been dejlected by the previous stroke, is now released, thus closing the valve s and shutting off the supply of gas to the burner.

It will be seen that the normal pressure eX- isting in the gas-conduit Within its limits between the maximum and minimum amount will not be able to actuate the lighting apparatus, as no gas will be admitted to the bell a until the valve i has been raised through the agency of an increased pressure predeterminedly sent through the conduit.

Instead of arranging the valves 1I and la inside the bell a, as shown, they might be arranged outside the same and suitably connected to said bell or a similar device in a manner to admit the gas,if an additional pressure is made to flow through the conduit, and to provide for the escape of the gas as soon as the additional pressure will cease.

We claim as our invention- 1. In an apparatus for lighting and extinguishing gas, the combination with the supply-pipe burner, pilot-lighter and valve controlling the fiow of gas to the burner, of an element movable under gas-pressure, connections whereby the movement of said element operates said valve, and means whereby on the increase of pressure in the supply-pipe gas is admitted to the said movable element to operate the same, and on the decrease of pressure said movable element is restored to normal position, substantially as described.

2. The combination with the supply-pipe, burner,pilotlighter and valve, of a gas-chamber having a movable Wall, connections from said movable wall for operating the gas-valve, a normally closed pipe leading from the supply-pipe to said gas-chamber, a normally open passage leading from said chamber to the open air, and means whereby excess of pressure in the supply-pipe will open thegaspipe and close the passage to the air substantially as described.

3. The combination with the supply-pipe, burner, valve and pilot-lighter, of a movable bell, connections therefrom to said valve for operating the latter, a gas-pipe leading from the supply-pipe to the gas-chamber within said bell, a gas-exit passage from said chamber, a valve closing said gas-pipe adapted to open under excess of pressure, a valve normally open for closing the exit-passage, and a rocking lever connecting said valves whereby they are alternately operated, substantially as described.

In testimony that we claim the foregoing as our invention we have signed our names in presence of two subscribing witnesses.
